The therapeutic monoclonal antibodies are very important tools to fight against the diseases especially in the field of cancer immunotherapy. Many immunotherapeutic antibodies are being used to treat cancer that target multiple different components of the cancer microenvironment. Cells with extracellular juxtacrine ligands [JL-cells] and extracellular juxtacrine receptors [JR-cells] form JL-cell-JR-cell interfaces that produce juxtacrine signals inside JR-cells. [76] Juxtacrine signaling unlike endocrine or paracrine signaling requires no release or cellular uptake of ligands. [76] Immune checkpoint inhibitors are soluble IgG antibodies that block juxtacrine ligand engagements with juxtacrine receptors on tumor or other immune cells. [77] Rapid Nobel Prize …

Abstract

Online Ultra-High Performance Liquid Chromatography-Charge Transfer Dissociation-Mass Spectrometry (UHPLC-CTD-MS) of Complex Mixtures of Oligosaccharides

Praneeth M. Mendis

Complex carbohydrates make up more than half the biomass on earth, and they are crucial to a wide range of processes in living organisms. When polysaccharides and glycans are enzymatically digested into manageable units called oligosaccharides, they typically consist of 2-20 linear or branched sugar units. The detailed structural analysis of oligosaccharides assists in the identification of structural and chemical properties of the polymers from which they derive. Tandem mass spectrometry (MS/MS) is a key technique used in oligosaccharides structural characterization. Within …
